IMPROVEMENT IN SHEEP-SHEAEIN G DEVIGE.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, J. K. ALWOOD, near the town of Delta, in the county of Fulton, and State of Ohio,

have invented a new and valuable Improvement in Cutting-Device for Sheep-Shearing; and I do hereby declare that the following is a full, clear, and exact description of thebonstruction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a top plan view of the front portion of the shear-case and cutting-device with cover removed.

Figure Z'represents the bottom of the front end of the shear-case, illustrating the semicircular improve ment or projection 13, in front of the dotted line d, with its fingers '0 v. I

Figure 3 represents the bladed wheel a a a, with its blades K K K K.

p The whole device consists of a metallic case, S, in the front end ofwhich there is a band or cord-wheel, which is connected, by means of cogs or teeth, or otherwise, with a. circular plate or disk, at a a, which revolves laterally, receiving its motion from the said cord-wheel Y, and is furnished with several double-edged blades, which project from its periphery, and are so adjusted as that they cut in either direction, corresponding with the direction of the wheels motion. The blades or knives K K K K just now mentioned, pass, in their circular motion, directly over a set of fingers, o 1), which are arranged in a semicircle-around the edge of a'semicircular. projection of the bottom of the shear-case S, and marked P, in front of the dotted line (Z, fig. 2.

The fingers 11 'v serve as stays for the fleece while the blades, in their circular motion, are clipping it, and also to press down the skin, and thus prevent its being wounded.

The cord-wheel Y and the shear-case S, excepting the semicircular projection P, are old, and not claimed in this petition.

The advantages of this device are these First, by its semicircular form in front, it can more easily be applied in and about cavities in the surface of a sheep, about the flank or neck, &.c.

Second, the motion is uniform and steady, obviating the quirering of an oscillating cutting-device, and also the necessity of more power required by sudden change of the direction of motion ;-thus the nerves and strength of the operator are greatly spared.

Third, the blades can be sharpened as easily as .the most simple bladein cutlery. Thisis a very great desideratum.-

Fourth, the blades can be literally worn out without injuring their shape, by shortening, as in other instruments of the kind.

Fifth, the blades can be replaced, when broken or injured, without the least difiiculty, and without any expense beyond the simple value of a solitary blade.

Claim.

Having thus described my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

1. The bladed wheel a a a, with its blades K K K K, substantiallyas described, for thepurpose specified.

2. The semicircular protuberance P of the shear-case S, in front of the dotted line d, with the fingers v 11, substantially as described, for the purpose specified.

3. The combination or connection of the bladed wheel a a a with the cord-wheel Y, so as to receive motion therefrom.

4;. The combination-of the several parts described, for the purpose of forming a cutting-device for sheepshearing.

In testimony that Iclaim the above, I have hereunto subscribed my name in the presence of two witnesses.

J. K. ALWOOD.
